[0002] During mining operations, it is often necessary to use a flameproof and intrinsically safe DC stabilized power supply to power other equipment. It is an electronic device that can provide a stable DC power supply to the load. It mainly uses the change of the power supply voltage or the load resistance to keep the DC output voltage of the regulator stable.

[0003] As the mining depth increases, the internal moisture content becomes higher and higher. The current existing method mainly uses desiccants and other moisture-absorbing fillers to adsorb moisture. However, the moisture adsorption effect decreases after the filler is saturated. The existing equipment is not convenient for observing whether the filler is saturated and cannot be replaced in time.

[0004] Therefore, a mine-used intrinsically safe DC stable power supply heat dissipation and dehumidification mechanism is proposed to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] When implementing: Figure 1-6 As shown, a heat dissipation and dehumidification mechanism of a mine-used intrinsically safe DC stabilized power supply comprises:

[0029] The power supply body 1 has a mounting plate 101 fixedly connected to the bottom of the power supply body 1. The top of the mounting plate 101 has a mounting cavity 102. The inner wall of the mounting cavity 102 has an exhaust slot 103 connected to the outside.

[0030] Dehumidification component 2, which is arranged inside the mounting plate 101 and is used to absorb moisture in the air and can also prompt the user to replace the dehumidification component 2 in time;

[0031] The heat dissipation component 3 is arranged inside the installation cavity 102 and is used to dissipate heat during the operation of the power supply body 1.

[0032] like Figure 1-6As shown, the dehumidification component 2 includes two placement slots 207 opened on the top of the installation plate 101 and symmetrically distributed. Evenly distributed air inlet slots 209 are opened on both sides of the inner wall of the placement slot 207. The air inlet slot 209 on the side away from the installation cavity 102 is connected to the outside world, and the air inlet slot 209 on the side close to the installation cavity 102 is connected to the installation cavity 102.

[0033] The inner wall of the placement groove 207 is slidably connected to a support plate 208 , the bottom of the support plate 208 is fixedly connected to a spring 210 , and one end of the spring 210 away from the support plate 208 is fixedly connected to the inner bottom wall of the placement groove 207 .

[0034] A placement shell 202 is provided on the top of the support plate 208 . The interior of the placement shell 202 is filled with a filler, which is a desiccant. The surface of the placement shell 202 is provided with evenly distributed ventilation holes. An indicator rod 203 is fixedly connected to the inner wall of the placement shell 202 .

[0035] A cover plate 201 for shielding the placement slot 207 is provided on the top of the mounting plate 101 . A through hole corresponding to the indicator rod 203 is opened on the surface of the cover plate 201 . An end of the indicator rod 203 away from the placement shell 202 passes through the through hole.

[0036] The airflow is introduced into the interior of the placement groove 207 through the air inlet groove 209. The air entering the placement groove 207 can pass through the ventilation holes on the surface of the placement shell 202 and come into contact with the filler. In this process, the moisture in the air can be adsorbed. The air adsorbed by the desiccant is then introduced into the interior of the installation cavity 102 through the air inlet groove 209 connected to the installation cavity 102. This can enhance the air exchange efficiency with the bottom of the power supply body 1, thereby achieving a dehumidification effect while enhancing the heat dissipation effect of the power supply body 1.

[0037] As the desiccant absorbs more moisture, the weight of the placement shell 202 can gradually increase, so that the placement shell 202 drives the support plate 208 to overcome the elastic force of the spring 210 and press the spring 210 downward. During this process, the placement shell 202 can drive the indicator rod 203 to move downward synchronously until the entire shell 202 shrinks to the inside of the through hole, indicating that the desiccant inside the placement shell 202 is saturated with adsorption, and the staff can replace it in time, avoiding the situation where the traditional desiccant is not replaced in time after being saturated with adsorption, resulting in a decrease in dehumidification effect.

[0038] like Figure 2 、 Figure 3 and Figure 5As shown, a knob 214 is provided on the top of the cover 201, and a mounting post 211 is fixedly connected to the bottom of the knob 214. Two symmetrically distributed blocks 212 are fixedly connected to the surface of the end of the mounting post 211 away from the knob 214. A spring 213 is fixedly connected to the surface of the mounting post 211, and the end of the spring 213 away from the mounting post 211 is fixedly connected to the inner wall of the cover 201.

[0039] A mounting hole 204 corresponding to the mounting column 211 is provided on the top of the mounting plate 101, a slide groove 206 is provided on the inner wall of the mounting hole 204, and a card slot 205 connected to the slide groove 206 is provided on the inner wall of the mounting hole 204, and the slide groove 206 and the card slot 205 are approximately "L"-shaped.

[0040] When replacing the desiccant inside the placement shell 202, it is necessary to first remove the cover 201. By rotating the knob 214, the mounting post 211 can be rotated, causing the block 212 to slide from the slot 205 to the connection with the slide slot 206. At this time, the rotation of the mounting post 211 can be released, and during the rotation process, the spring 213 can be tightened by the mounting post 211. Then, by pulling the cover 201 upwards, the mounting post 211 can be driven to separate from the mounting hole 204, so that the filler inside the placement shell 202 can be replaced.

[0041] like Figure 1-6 As shown, the heat dissipation assembly 3 includes a plurality of evenly distributed thermal conductive strips 301 fixedly connected to the inner wall of the installation cavity 102, the top of the thermal conductive strip 301 contacts the surface of the power supply body 1, and the interior of the installation cavity 102 is provided with a fan 302 located at the bottom of the thermal conductive strip 301.

[0042] By starting the fan 302, the outside air can be guided to pass through the air inlet slot 209 and the placement slot 207 and dehumidify it under the action of the dehumidification component 2, thereby increasing the air exchange efficiency in the installation cavity 102, so that the heat generated during the operation of the power supply body 1 can be discharged through the exhaust slot 103, and the setting of the thermal conductive strip 301 can absorb the heat generated during the operation of the power supply body 1, accelerate the heat exchange efficiency, and improve the heat dissipation effect.

[0043] When the present invention is in use, the outside air is guided into the interior of the installation cavity 102 by starting the fan 302. During this process, the moisture in the air can be adsorbed under the action of the dehumidification component 2. The dried air is introduced into the interior of the installation cavity 102 to increase the air exchange efficiency inside the installation cavity 102, so that the heat generated during the operation of the power supply body 1 can be discharged through the exhaust slot 103, and the setting of the thermal conductive strip 301 can absorb the heat generated during the operation of the power supply body 1, accelerate the heat exchange efficiency, and improve the heat dissipation effect.

[0044] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
